Thanks, but you left most of the old fluid still in there with that method. I'm going to let it run out of the coolant line and get as much of the old fluid out as possible.
You won't regret it. Its honestly super easy and very gratifying knowing you're getting all the old fluid out except maybe a few tablespoon fulls. My fluid looks perfect even after 30k miles on the new synthetic fluid I put in it. (but I changed it anyway) And that's on my old 08 model with 168,000 miles on it. I also added a bypass filter (also pretty easy to do) from the line you pump the fluid out of, so now I have some real filtration on the tranny too. I did this on both our CX9's.
